We are traveling with family. 2 different rooms.. We are arriving late so that's one day of dining credits we won't need. We are also spending a day visiting offsite so doubtful we'll use a TS credit that day. We leave early the day of departure. Using Magical Express. I know we can use leftover dining credits for snacks but since part of the family isn't leaving until late can we just give them our Magic Bands before we leave and let them use up the rest of our credits ? We don't need to keep our Magic Bands with us on departure day do we?
